Brawn had money for 2009. Honda made sure the team survived for at least one year, As did Bernie Ecclestone by giving the team an advance on their concorde money.
But that was not enough to maintain the like of Zander et al. So alot of people left the team.
Also Stuttgart were looking at ways of going alone, for any number of valid reasons. Spygate, Liegate and then the split of road car ideologies.
Now the underlying speculation of benz involvement.
Mercedes stepped in to provide engines as a front for FOTA. Ferrari also offered engines but Brawn decided on the Benz units.
Once the season got underway the team sported Virgin branding, as the team gained more wins the price of buying the team went north, and Virgin got cold feet and got into bed with Manor GP in August 09. Remember this is all in the backdrop of the credit crunch, where sponsors were extremely hard to find.
This left Brawn with very little option. So he turned to Mercedes and negotiations would only have been seriously active around the time Virgin intimated they wouldnt be doing a deal.
Mercedes had a problem though. They were laying off staff left right and centre as the credit crunch set in. Enter Aabar investemnts(daimler shareholders)who are cash rich and the real reason why Mercedes went racing again.
Without these guys, Mercedes would only be supplier to a BGP002.
And finally, There is the end of year reports which shows where money has been spent. Brawn did not recieve one euro prior to november 2009.
